ADJUSTABLE FIRE-POT.

Specification of Letters Patent.

Patented April 24, 1906.

Application iletl April 6, 1905. Serial No. 254,208.

To fr/ZZ Lf/wm it may concern:

Be it known that I, CHARLES H. GATCHELL, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful .improvements in Adjustable Fire- Pots ,1 and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the saine.

This invention relates to improvements in adjustable partitions for stove and range fireboxes.

The object of the invention is to provide a partition of this character by which the firebox of a stove or range may be shortened, whereby only a portion of the same may be used, thus permitting a small fire to be made in the box.

A further object is to provide means whereby that portion of the grate not being used for the fire may be closed, thus causing all the draft to pass through the portion of the grate holding the fire, means being provided whereby the partition-plate may be increased in width to fit within fire-boxes that are wider than the main portion of the plate.

iYith these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a longitudinal vertical sectional view through the fire-box of a range, showing the application of the invention thereto. Fig. 2 is a detail perspective view of the device removed from the fire-box. Fig. 3 is a vertical sectional view through the same, taken on a line with the adjusting mechanism of the supporting-plate. Fig. 4 is a side view showing the parts in folded position, and Figs. 5 and 6 are detail plan views of different forms of partition-plates.

Referring more particularly to the drawings, 1 denotes the partition-plate, on one side of which, near the lower edge, is formed a pair of laterally-projecting apertured ears or lugs 2, which are adapted to engage an apertured lug 3, formed on the section 4 of an adjustable supporting-plate 5. The section 4 of the supporting-plate is slidably mounted on a lower section 6, said section 6 being provided on its edges with upwardly and inwardly projecting flanges 7, which are adapted to engage the opposite edges of the section 4, thereby holding the same in sliding engagement with the section 6.

On the outer side of the jnutition-plate 1 above the lug 2 is hingedly connected the upper end of a brace-bar S, the lower end of which is bent at an angle and is provided with a T-shaped slot t), adapted to engage a headed pin or stud 10, arranged on and proj ecting upwardly from the section 4 of the supporting-plate 5, whereby the partition-plate 1 is held in an upright position at right angles to the supporting-plate.

In order that the sections 4 and 6 of the plate 5 may be prevented from being entirely separated or slipped apart, one of the guide- `flanges 7 is provided with an offset or proj ection 12, which is adapted to be engaged by a pin 13, projecting upwardly from the section 4, thus limiting the movement of the section 4 in one direction. In order to limit the movement of said section in the opposite direction, a pin or stud 14 is arranged adjacent to the outer edge of the section 6 to form a stop against which the outer edge of the section 4 strikes when the plates are adjusted together.

In order to hold the sections 4 and 6 of the plate 5 in adjusted position, the upper section 4 is provided with a llat spring 15, on the free end of which is arranged a downwardlyprojecting stud 16. This stud 16 is adapted to be forced by said spring through an aperture 17, formed in the plate-section 4, and into engagement with one of a series of apertures 18, formed in the lower plate-section 6. The spring 15 is turned upwardly at its free end to form a finger-piece 19, whereby the same may be lifted to disengage the stud 16 from the apertures 1S, thus allowing the sections 4 and 6 to be adjusted to increase or decrease the length of the supporting-plate 5.

On one side of the partition-plate 1 adjacent to one edge of the same is arranged a supplemental plate 20, in which is formed horizontally-disposed slots 21, engaged by retaining-screws 22, secured in the partition-plate 1. By means of the slots 21 and screws 22 the supplemental plate 2O may be shifted to increase the width of the partition-plate 1, thus enabling the same to be adjusted to the width of the fire-box in which it is arranged.

In arranging the partition within the iireboxes the supporting-plate 5 is placed upon the grate at one end of the same, after which the sections 4 and 6 thereof are slipped apart IOO IIO

plates assist in the ventilation or draft of the ire.

In forming the partitions the partition plate 1 will be constructed of considerablyheavier material than the supporting-plates,-

so as to resist the heat from the fire-box and to prevent the same from becoming warped by the heat. In practice it is intended to form the partitions in standard sizes to correspond with the standard sizes of the ireboXes of different ranges or stoves. The adjustable supplemental plate 2O on the partition-plate 1 is provided to enable the same to be snugly fitted within odd sizes of fire-boxes.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention willY be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An attachment of the class described,

comprising a base plate composed of two overlapping sections, one of said sections being provided at its edges with anges adapted to receive the other and to hold the sections in sliding engagement, and the lower section being provided with a series of apertures, a spring-projected pin carried by the upper section and adapted to engage either of said apertures, a partition-plate hinged to said upper section, and a brace adapted to hold said partition-plate in an upright position.

2. An attachment of the character described, comprising a base-plate composed of upper and lower sections, guide-anges formed on said lower sections to receive the upper section, whereby the latter is held in sliding engagement with the lower section, a stoppin arranged on said upper section to engage an offset on one of said guide-anges to prevent the separation of said sections, a springprojected stop-pin carried by said upper section to pass through a hole in said upper section, said lower section having a series of holes therein, with one of which said spring-projected stop is adapted to engage, a partitionplate hingedly connected to said upper section, a hinged brace-bar to support said partition-plate in an upright position, and a supplemental plate adjustablv connected lto said partition-plate, whereby the width of the latter may be increased, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
